Built-in oven



United States Patent O ice 3,270,736 BUILT-IN OVEN Eugene J. Barnett,Mansfield, Ohio, assigner to Westinghouse Electric Corporation, EastPittsburgh, Pa., a corporation of Pennsylvania Filed May 28, 1964, Ser.No. 371,051 3 Claims. (Cl. 126-19) The present invention relates tocooking ovens and more particularly to a -domestic cooking oven of thetype adapted to be built into surrounding cabinet structures.

The popularity of the so-called built-in cooking oven is wellestablished. Many of the oven arrangements now being built into thesurrounding cabinet or wall structures of the modern kitchen are alsoprovided with broiler facilities and problems have existed in connectionwith the -disposal of the heat vapors without damage to the surroundingWall surfaces,

It is a principal object of the present invention to provide an improvedarrangement of built-in oven construction having an extremely simple yeteffective heat vapor deflector and heat insulating structureincorporated in the trim -adjacent the oven door.

Another object of the present invention is to provide an improved trimstructure for the door of a built-in oven such 4that the surfaces of thetrim members next adjacent the surrounding wall surfaces do not becomeheated enough to scorch or otherwise mar such Iwall surfaces.

In accordance with the invention the trim surrounding the oven dooropening and in particular the door opening upper edge is comprised of afirst planar heat deflecting ledge member having upper and lowr planarsurfaces with its lower planar surface adjacent the upper edge of thedoor opening. The planar surfaces of the heat deflecting ledge extendoutwards from the plane of the oven door in a manner to -deect heatvapors originating in the oven away from the surrounding cabinet wallsurfaces near the plane of the oven door opening. A spacer panel of heatinsulating material such as glass or decorative ceramic is positionedywith a lower edge surface extending in Contact with the upper planarsurface of the deflector ledge. The final upper or outer trim member ofmetal or the like which is in contact with the surrounding cabinet wallsurfaces is supported from the lower deector ledge on spacers with theheat spacer panel floating therebetween. The provision of the spacerpanel and the heat deflector ledge prevents the upper or outer trimmember or the surrounding wall surfaces from being heated by eitherconduction or convection to a degree to cause discernible damage.

Further objects, features and the attendant advantages :of the inventionwill be apparent with reference to the following specification anddrawing in which:

FIGURE 1 is a perspective elevation of a built-in oven With trimembodying the heat deflecting arrangements of the invention; and

FIG. 2 is a fragmentary detail on the line II--Il of FIG. 1.

Referring to the drawing, the oven cabinet liner, a fragment of which isshown at is arranged to be built into a surrounding wall or cabinetstructure 4such as fragmentarily shown at 11. It will be noted that whenthe oven liner 10 is built into the surrounding wall 11', the plane ofthe oven door opening 12 is generally in the plane of the wall surface11. As shown by FIG. 2 of the drawings, and particularly when the ovendoor is opened, heat vapors tend to rise from the oven adjacent the wallsurface 11 but they are deflected by the planar heat deflector ledge 14of the invention which extends across the upper edge surface or the dooropening 12.

Of course, the heat deflector ledge 14 which is formed of any suitablematerial such as chromium plated metal 3,276,736 Patented Sept. 6, 1966would become quite warm by contact with the oven liner 10 and the heatvapors from the ovenand in accordance with the invention a heatinsulating panel 1-5 which may be formed of glass, decora-tive ceramicor other vitreous material is positioned with its lower edge surface 16in contact with the upper planar surface of vthe heat detiector ledge14. A final upper or outer trim molding 17 of any suitable material suchas chromium plated metal is secured along the upper edge -surface 18 ofthe spacer panel 15 by means of the heat insulating spacer tubes 21 andpins 20 and is adapted to contact the surrounding wall surface 11 whenthe oven liner is built into the wall as shown.

The flow arrows of FIG. 2 show how the heat vapors are deflected `by theheat deector 14 to be mixed with relatively cooler surrounding aircurrents and to be dispersed generally away from the wall surface 11.Although the deflector ledge 14 may itself become heated, the spacerpanel 15 of heat insulating material will prevent the outer trim memberor molding 17 from becoming heated sufficiently to damage the wallsurface.

As previously mentioned, the upper trim member 17 and the heat spacerpanel 15 may be secured in place by one or more pins 20 extendingthrough heat insulating spacer bushings 21 into retaining means such asthe spring clip 22 on the oven liner 10 as shown. Rubber bushings orcushions 23, 24 may also be provided to cushion the panel 15 in a oatingarrangement such as to prevent breakage of the panel during shipment ofthe oven. The amount of heat conducted by the relatively small and fewpins such as the pin 20 is immaterial. Of course the invention is not tobe limited to a particular arrangement for securing the assembly such asthe pin 20 and various other modifications will occur to those skilledin the art.
